I've used it for years with mixed results. I think you have to pay if you want to get any results. Also, it's better if you're younger and hung. I'm old now, and not a hunk, so nothing last time I tried. I met a few ladies, regular women, and had some fun years ago.
So, I'm not sure if it's really worth it. You might give it a try. You might get some without having to pay as much to see a pro.
